Getting error when running Systemizer ...

This is the error/s I get, not sure what I'm doing wrong. Does it have something to do with the JDK? I checked the console and it's installed. I thought pointed IntelliJ to the right place but maybe not? Really confused here.

Exception in thread "main" java.lang.ClassNotFoundException: com.teamtreehouse.Main at java.net.URLClassLoader$1.run(URLClassLoader.java:366) at java.net.URLClassLoader$1.run(URLClassLoader.java:355) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:354) at java.lang.ClassLoader.loadClass(ClassLoader.java:425) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:308) at java.lang.ClassLoader.loadClass(ClassLoader.java:358) at java.lang.Class.forName0(Native Method) at java.lang.Class.forName(Class.java:190) at com.intellij.rt.execution.application.AppMain.main(AppMain.java:122)

Can you post your code so we can see where the error may have occurred?

When you created a new project in IntelliJ. Did you create the project exactly as Craig did or did you add your own custom project name?

What did you name it? and what is the name of your class file that holds the public static main method in it?

If you could post your code, using the Markdown Cheatsheet below, that would also be helpful.

If you copied the code directly from Teacher's notes then you have a mismatch between what the Class is named and what the file is named. The class name defaults to main (the file name) in intelliJ but in the teacher's notes it is named Systemizer. That is probably your issue
